Serial No. 49,319.

The main objects of this invention are First, to provide an improvedcombined internal combustion engine cooling fan and water circulationpump which maybe assembled and handled as a unit, 'and installed as aunit.

Second, to provide an improved structure having these advantages whichalso has a force feed lubricating means. Third, to provide a unitarystructure of the class described in which'the water is efl'ectivelyprevented from mixing with the lubricant.

Fourth, to provide an improved pulley structure for units of the classdescribed.

Objects pertaining to details and economies of m invention willdefinitely appear from the etailed description to follow.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing forming a part of thisapplication, in which:

Fig. I is a fragmentary view mainly in longitudinal section of astructure embodying the features of my invention, the same being shownin operative relation to the water jacket of an internal combustionengine and the circulating connection being omitted. The section istaken on line 1-1 of Figs. II

and III.

Fig. II is a detail cross section on a line corresponding to line 22 ofFig. I.

Fig. III is a detail cross section on a line 5 corresponding to line 33of Fig I.

. Fig. IV is a fragmentary view pa tially in longitudinal section on aline corresponding to line 4--4 of Fig. V of a modified embodiment of myinvention. Fig. V is a fragmentary transverse section on a linecorresponding to line 5-5 of Fi IV.

Fig. VI is a fragmentary longitudinal sec- I tion on a linecorresponding to line 66 of Fig. IV.

- In the drawing the sectional views are taken looking in the directionof the little arrows at the ends of the section lines and similarnumerals of reference indicate similar 5 parts in all of the views.

Referring to the drawing, 1 represents the waterjacket ofan internalcombustion engine. My improved fan and circulating pump unit comprises acylindrical member 2 chambered at 3 to provide a lubricant receptacle.At its inner end the body member has a transverse partition 4 carryingthe packing gland casing 5 which in the embodiment illustrated in Fig. Iis internally threaded to receive the packing gland 6. K

The head closing the outer end of the body comprises an inner headmember 7 having the inwardly projecting bearing 8 thereon. This innerhead member is recessed on its outer face at 9 to receive the gears 10and 11 constituting a gear'pump. The outer end plate 12 constitutes theouter member of the casing. A passage 52 is provided leading from thenip or meeting point of the gears to the spindle. An inlet passage 53 isprovided at the bottom of the gear 11.

The gear 10 is mounted on the spindle 13 supported in the bearing 8while the gear 11 is mounted on a stub shaft 14 carried by the innerhead member. The inner end of the spindle 13 projects through thepacking gland and the impeller 15 is mounted thereon. The outer end ofthe spindle 13 projectsto receive the hub 16 on which the fan blades 17are mounted and also the pulley. g

This pulley in the embodiment illustrated comprises a main pulley member18 whiclrhas a flange 18 at its outer end secured to the hub 16 and aninclined pulley flange 19 at its inner'end, the pulley member beingarran ed to embrace the outer end of the body 2. he supplementary pulleymember 20 is sleeved upon the main pulley member and has a flange 21 inopposed relation to the flange 19. A coiled s ring 22 yieldingly s'upoports the pulley mem ber 20 so that any wear on the belt isautomatically taken up and the belt is automatically tensioned owing tothe V -shape of the pulley, fan belts now commonly in use in this,relation being designed as for pulleys having V-shaped rims. I p Thelubricant circulating pump is similar to that of my Patent No.1,378,587, dated May 17, 1921.

To render the packing more effective and to prevent water reaching thelubricant chamber through the packing 23 the gland 6 is provided with adrain passage 24 communicating with the drain opening 25. The gland 6may be adjusted through the openings 27 by means of a suitable tool, thegland having notches 29 in its periphery to facilitate assist inretaining the lubricant. The plug 35 is provided for draining thelubricant chamber.

In the modification shown in Figs. IV, V and VI the packing gland 37 isautomatically adjusted bymeans of the coiled spring 38 which engages theshoulden 39 on the gland and a shoulder 40 on the bearing 8. Thelubricant pump in this embodiment is the same as that described and,therefore, the

details are not further illustrated.

The inlet connection 41 corresponds to the inlet connection 30, beingdisposed in a general tangential relation to the chamber 51 at the innerside of the impeller. The packing gland has a series of radial openings42 opening to an annular groove 43 which communicates with the drainpassage 44.

The main pulley member 45 is in this embodiment provided with a pin .46engaging the slot 47 in the adjustable pulley member 48 so that the pullof the belt on the pulley member 48 tends to carry the flange 49 towardthe flange'50, thus performing the function, broadly considered, of thespring 22.

I have illustrated my improvements in an embodiment which I have foundhighly satisfactory. I have not attempted to illustrate or describeother modificatlons and adaptations which'I contemplate as I believethis disclosure will enable those skilled in the art to embody or adaptthe same as desired.
